摘要
Carbon nano-particles were synthesized using an arc-discharge apparatus. Magnetic-metal filled nano-capsules were segregated from nonmagnetic carbon particles using a magnet. TEM, XRD, EDS and Raman scattering spectroscopic examination revealed that a magnetic iron particle, 10-50 nm in diameter, was encapsulated in each carbon nano-capsule. These magnetic-metal filled carbon nano-capsules were then coated individually with amorphous silicate to provide additional oxidation protection. These nano composite particles ranging from 100 to 300 nm in diameter can be dispersed in water solution and aligned or spatially arranged by a magnet. (C) 2002 Elsevier Science Ltd and Techna S.r.l.
